Moderator Cynic Posted May 7, 2011 Moderator Share Posted May 7, 2011 Just got back from Rufforth Auto jumble Nr York,well glad I did,nt travel along way ,saying that was worth entrance fee of £4.00 picked up a pair of nice Renthal bars for 6 quid ,a new DT MX 6volt battery for 12 quid inc acid(the only thing ticked of my list!),and poss best buy DT175 MX front exhaust pipe for a fiver,back mounting lug cut off but very little rust and never repaired so was def worth a punt, I was not 100% sure it was a DT exhaust but suppose thats the thing with Autojumble you take the chance. well back to Ebay. By the way got a responce from a breaker in the US for a pair of forks $150 + shipping he,s having a laugh !!!! Don't worry about the rear mount mine has not had the bracket that it fits to in my ownership and i've never had any issues. Its probably a lot easier to fit with the lug cut off TBH.

Moderator Airhead Posted May 10, 2011 Moderator Share Posted May 10, 2011 Phil it's a long time since I delved into my headlamp bowl but what I expect to see is Multi block connectors to L&R handlebar controls Multi block connectot to ignition switch bullets to L&R indicators Multi block to idiot lights (clocks) bullets to headlamp bullets to speedo illumination Multi block to fron stop lamp switch It's all in the wiring schematic. Can you tell us a bit about the loom...is it new...is it a 2k4 version? Link to comment Share on other sites More sharing options...

philmountains Posted May 14, 2011 Author Share Posted May 14, 2011 Hi Old git "I realy dont like calling you that !" well I have gathered loads of bits over the years for the DT, remember I started this whole project in 1995 when was I given a box of large lumps for free, and the loom was not part of this so ? however I have 3x looms "at present" and one is definatly for 125mx as it has not got wiring for CDI whereas the other 2 including one now fitted has, might be wrong here but sure 125mx had points? yeh I have had quite a few of probs" guesswork" with wiring so far and is not finished/tested yet no "6volt battery charger" my last prob is the red and yellow wire, cannot find anything in the cliymer or Haynes for this wire ? and thats from ignition harness so god knows ? Note. oldgit not 1 scotch lock so far Going a bit of subject has anyone used the 2.5 mm aluminiun STICK welding rods as have some repairs to do on barrel only ever welded aluminium with Tig and this was years ago!!!! and was bloody difficult,I did not realy have the knack of it " I once was a coded gas and arc welder, ,also bent fins any advise ?

Call me Paul then Early 125's had points later ones had CDI One of the Haynes manuals is not so good, it's the one with an orange front cover border, if you look at the ig switch it shows as 4 wire only which is plain wrong as we have positions 1 2 and 3 withe key. Cynic put me onto a better manual wich also shows the later version wiring diagram.. it has a brown border and a twinshock picture on the front cover...ISBN 1 85010 300 3 Link to comment Share on other sites More sharing options...

philmountains Posted May 16, 2011 Author Share Posted May 16, 2011 Hi "Paul"yeahh it,s the oldHayness up to 1980 I have also got the Clymer up to 83 .Starting to think this loom is more bother than it worth ? Well this might be a case of after the horse has bolted, as cut the wiring now(too Bloody close to multi block) Paul/Cynic you know you said it was a newer loom !!!!! well whilst thumbing old MMCs and DT articles noticed that the newer post 1980s have a extra on/off switch, is there by any small chance there are 2 sub harneses coming from the left hand switch there must be 2 more wires ,have a look at the pic this switch is the same as i have fit Also have a look at these 2 CDIs the biggy is defo 78 175mx vintage i have 2 more at this size cannot read Nos on side so reckon this needs a bit of sorting before I put fire to a engine Link to comment Share on other sites More sharing options...
Moderator Airhead Posted May 16, 2011 Moderator Share Posted May 16, 2011 Not sure on the switch issue but there are two versions of CDI, one is 6 wire and one is 7 wire, the presence or absence of a RED is the difference, early bikes had two source coils in the magneto...the RED connects to source coil 2 on these.

Thanks Paul yeh there was a extra red on that CDI ,just read NEOs post,s on 12v conversion looks good a credit to him for this, wish I had not bought new battery & rectifier the other week, cause when do get bike running will be riding in dark to work and back on unlit roads, and this def looks the biz have you guys switched over ?

Moderator Airhead Posted May 19, 2011 Moderator Share Posted May 19, 2011 .......have you guys switched over ? No mate I dont use mine in the dark on unlit roads, dont expect much even if it is 12v. My DTR is 12v and a simillar setup, ie headlamp straight from magneto, kinda glows different shades of orange for different engine speeds Link to comment Share on other sites More sharing options...
